Ak.zip Review

The primary purpose of ak.zip is to take several arrays and "zip" them together so that each element of the resulting array is a record (like a row in a table) containing values from each input array.

# Example: Creating a record array with fields "x" and "y" import awkward as ak array = ak.zip({"x": [1, 2, 3], "y": [1.1, 2.2, 3.3]}) # Result: Use code with caution. Copied to clipboard ak.zip

: If you pass a list or tuple of arrays instead of a dictionary, it creates an array of unnamed tuples. The primary purpose of ak

: It is frequently used when reading from or writing to ROOT files (standard in physics) to ensure that attributes with the same "raggedness" (like jet or muon properties) are grouped correctly for storage. How to concatenate and interleave arrays : It is frequently used when reading from

: In comparison to Pandas, where concat(axis=1) adds columns, ak.zip is the equivalent for adding fields to an Awkward Array record .

: By passing a dictionary to ak.zip , you can create named fields.
